RECOMMENDED INFORMATION
This is a drop in replacement for your lead-acid battery and will not require any changes to your stock charging system. It can be placed on electric scooters, bicycles, UPS backup systems and wheelchairs anything that uses a sealed lead acid battery. LifePO4 contains no poisonous lead, no acid, and does not create gases during charging, as traditional lead-acid batteries do. Compared to lead-acid, lithium iron phosphate batteries are also extremely light, have much lower self-discharge, non-sulfate, and are environmentally friendly.
